Specification of Letters Patent. Patented May 24, 1921.

Application filed March 20, 1920. Serial No. 367,861.

To all whom it may concern:

Be it known that I, OHIO C. B. CLARK, a citizen of United States of America, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Spotlights, of which the following is a specification.

This invention relates to a spot-light, and comprehends a novel construction and arrangement of parts whereby the lamp can be easily adjusted in a, vertical or horizontal plane through the instrumentality of a handle disposed in convenient reach of the user.

In carrying out the invention, the lamp proper is supported by a pivoted arm for vertical adjustment, while the arm is supported by a rotatable member provided with -a slot through which the arm projects, this slot being covered by a yieldably supported shield to. protect the working parts of the invention within the rotatable member, from the bad effect of inclement weather conditions, the shield also assisting in retaining the lamp in normal position.

The nature and advantages of the invention will be better understood when the following detailed descriptions are read in connection with the accompanying drawings, the invention residing in the construction and combination and arrangement of parts as claimed.

In the drawings forming. part of this application, like numbers of reference indicate similar parts in the several views wherein:

Figure 1 is a side elevation of the invention. Fig. 2 is a vertical sectional view.

Fig. 3 is a similar view taken at right angles to Fig. 2.

Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 1 with the lamp omitted.

Fig. 5is a similar view taken on line 5-5 of Fig. 1.

Rei'erring to the drawings in detail, 10 indicates generally the lamp which is supported for vertical and horizontal adjust ment in the manner to be presently described.

The invention makes use of spaced inner and outer casings of a cylindrical formation in cross sections, as indicated at 11 and 12 respectively. The bottom of the outer casing 12 is removable. This bottom being indicated at 13, and preferably threaded into the casing as shown. Arranged within the casing-l2 adjacent each end is a disk 14, the latter and the corresponding ends of the 1111181 receptacle 11 being formed with grooves 15 for the reception of ball bearings or the like 16. The inner casing 11 is nlounted for partial rotation within the outer casmg, andturns on the bearings 16 as will be readily understood. The inner and outer casings are provided with alined opcning s 17 and l8 respectively adjacent each end, and PIOJEC tIIIg through these openings, and from opposlte sides of the structure are upper and lower arms 19 and 20 respectivel Disposed within the inner casing 11 tbr opening 17, is a plug,21 having an opening registering with the opening 17 for the reception of the adjacent arms, the arms 19 and 20 being pivoted as at 22 within the plugs 21. As shown,- these arms 18 and 20 project within the casing 11 beyond the vertical axis, and also project an appreciable distance beyond the outer casing'atthe opposite sides thereof. A link 23 pivotally-connects the corresponding inner extremities of the aIms19 and 20 so that pivotal movement is imparted to these arms simultaneously in a manner to be presently described. The arm 19 is fitted within a socket 24 of the lamp 10 and secured thereto in any suitable manner. Detachably associated with] the arm 20 is a handle 25 through the instrumentality of which the lamp 10 is adjusted. By'reason of the construction thus far described, it is manifest that by pulling up upon the handle 25 the arm 20 is rocked about its pivot to move the link 23 downwardly within the casing 11, consequently moving the arm 19 upon its pivot to move the lamp 10 upwardly. Again, by depressing upon the handle 25, the arm 20 is moved upon its pivot in a mannerto move the link 23 upwardly in the casing 11, and consequently imparts a pivotal movement to the arm 19 so that the lamp 10 is moved downwardly. By moving the handle at 25 through the opening 18 of the outer casing 12, either to the right or left, the inner casing 11 is rotated and the lamp 1O consequently adjusted in a horizontal plane: The structure in its entirety can be conveniently supported upon a wind-shield of a motor vehicle or any other fixed part of the machine by means of a clamp 27 of the usual Well-known construction, or the casing 12 may be threaded exteriorly as at 28 to accommodate a supporting annulus 29.

In order to exclude rain, snow, dirt or other foreign matter from gaining access to the inner casing 11, I provide each of the arms 19 and 20 with a shield 30 which is in the form of an arc-shaped plate and having an opening through which the adjacent arm projects. The shield 30 is of such size as to cover the opening 18 in the outer casing 12 and is supported from the inner casing 11 by means of the springs 31. The shields 30 not only serve the purpose mentioned, but by reason of their resilient connection with the inner casing 11, also tend to maintain the arms 19 and 20 and their associated parts in normal position.

The wire connection for the lamp is indicated at 32'and passes through an opening in the outer casing 12 and through the space between the inner and outer casings through the bottom of the outer casing to a suitable switch on the dash-board or elsewhere.

While it is believed that from the foregoing description, the nature and advantages of the invention is readily apparent, I desire to have it understood that 1 do not limit myself to the details herein shown and that such changes may be resorted to when desired as fall within the scope of what is claimed. I

hat I claim is 1. A device of the class described comprising a support, a casing rotatably mounted thereon, parallel arms pivoted within the casing and PIOJGCtlDg therefrom at opposite sides, a link connecting the corresponding extremities of said arms, a lamp carried by one arm, and a handle carried by the other arm controlling the pivotal movement of the lamp for vertical adjustment, and the partial rotation of the casing for the purpose specified. 7

2. A device of the class described comprising an inner and outer casing, means for supporting the outer casing, the inner casing being rotatably mounted within the outer casing, a lamp carried by the inner casing and mounted for pivotal movement vertically, and means for'moving' the lamp on its pivot or partly rotating the inner casing for the purpose specified.

3. A device of the class described comprising inner and outer casings, the inner casing being rotatably mounted, arms pivoted within the inner casing and projecting through openings in the outer casing at opposite sides thereof, a lamp carried by one of-said arms, means for moving said arms in unison upon their pivots, whereby the lamp is adjusted vertically, a shield surrounding each arm and interposed between the respective casings to cover the opening in the outer casing, means for rotating the inner casing, and said shields being carried by the inner casing.

4. A device of the class described comprising spaced inner and outer casings, the inner casing being rotatably fitted within the outer casing, said casings having alined' openings, spaced parallel arms pivoted within the inner casing and projecting through said openings, a connection between the arms whereby the latter are simultaneously moved upon their pivots, a lamp carried by one of the arms, a handle carried by the opposite arm for controlling the pivotal movement thereoi and for rotation of said inner casing, a shield surrounding each arm and interposed between the casings, to cover the openings therein and yieldable means for supporting said shields from the inner casing.

In testimony whereof I ai'fix my signature.
